【OG20-P578-663题】Boreal owls range over a much larger area than do other owls of similar size. Scientists have hypothesized that it is scarcity of prey that leads the owls to range so widely. This hypothesis would be hard to confirm directly, since it is not possible to produce a sufficiently accurate count of the populations of small mammals inhabiting the forests where boreal owls live. Careful study of owl behavior has, however, shown that boreal owls do range over larger areas when they live in regions where food of the sort eaten by small mammals is comparatively sparse. This indicates that the scientists' hypothesis is not sheer speculation.

In the argument given, the two boldfaced portions play which of the following sheer speculation

A

The first presents an explanatory hypothesis, the second states the main conclusion of the argument.
分析A选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

B

The first presents an explanatory hypothesis;the second presents evidence tending to support this hypothesis.
分析B选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

C

The first presents an explanatory hypothesis, the second presents evidence to tending to support this hypothesis support an alternative explanation
分析C选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

D

The first describes a position that the argument opposes, the second presents evidence to undermine the support for the position being opposed
分析D选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

E

The first describes a position that the argument opposes; the second states the main conclusion of the argument.
分析E选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

又大又圆肉包打狗后没了

第二个黑体前面however是转折hard to confirm directly的，也就是however后面的内容提供了直接的证明。

重点在于看懂最后一句，“说明科学家的假设不是纯粹的猜测”，即黑脸2是supportive

要么看懂scarce和sparse都是稀少的意思，说明黑脸12方向一致；要么看懂最后一句里的sheer speculation。

猜想内容--很难确认-- however study show that……（study内容）--最终结论 A.第二粗体不是最终结论 B.第一句是一个假设，第二句是对假设的支持 C.第二句没有证明另外一种解释 D.第一句不是反驳的position，只是提出猜想；第二句不是削弱对反对的position的支持 E.第一句不是反驳的position，只是提出猜想；第二句不是main conclusion
